This invention relates to a closure for the filling necks of motor vehicle radiators, gasoline tanks, and the like, and has for its object an improved organization of parts, which,

while sacrificing none of the advantages in-- herent in the present screw-threaded means for securing the cap to the top of the filling neck, provides for a permanent attachment of the cap thereto so that it can neither be m carelessly lost when unscrewed, nor easily stolen. ll/ly improved structure not only meets these requirements, but as well so positions itself relatively to the filler neck when in unseated position therefrom as to he entirely out of the way of any hose nozzle or similar-fluid delivery medium which it may be desired to insert in the open top of the filler neck,

in the drawing:

Figure l is a plan view ofthe under face of the cap, with its attached and cooperating parts in looking position.

Figure 2 is a similar plan view of the under face of the cap, showing the parts in unlocked position as regards the manually efiecmd rotation of the cap on the filler neck.-

Figure 4: is a perspective of the filler neck and of my improved closure cap, the latter being shown in displacedposition from the former and at one side thereof.

Figure 5 is a sectional elevationalview it is taken, to Figure 3, ut showing the clo-' sure cap in the thrown-to-one-side position shown in Figure 4. V

Figure 6 is a similar sectional elevational view, showing the filler neck and closure cap in the relative positions occupied by them when the displacing movement of the cap therefrom or its replacement thereon is about half completed.

Figure 7 is a fragmentary erspective of a part of the ca -anchoring 1i designed to bring out a pre erred-method of efiectmg the hinged anchorage of the lower end of the link to the filler neck.

posite end of this link is similarl secured as by projecting points 'tured ear pieces E which form the end perpoint H with t A indicates fragmentarily the wall of a motor vehicle radiator or of a asoline tank, from which rises tahe filler nec B. The top edge of this neck is preferably inbent somewhat, asindicated at B, partly in order to form a curved, non-cutting edge surface upon which the-washer K of the tiller cap G may rest, but as well to provide through perhaps 90 of its extent a further inbentflange B of. slightly s .iralled inclination for coopera-- tive int/erloc ing with an attached part of the filler cap G which will be later referred to.

Generally opposite to this spirally inclined portion B, the flange B is also formed with a further projecting ear or tongue 13 whose ends B are formed into the pintled or trimnioned form shown most clearly in Figure 7, for hinging or pivoted engagement through the overhent ears D of the link D. The c 2 to apertions of the fbracltet or securing clip E, which is secured in the approximate center of the under face of the cap G by means of the rivet F. @i course ordinary pivot pins could be used as hinging pintles in place of the integral ears I) and B here shown, but the cost of such a construction would be greater and such an assemblage could more easily be separated it the the t of the cap were intended.

Also similarly secured to the cap G by the rivet F is the central portion of the contoured resilient clip piece H, one end of which as H is adapted to frictionallyengage under the spirally flanged 'part B when the cap is forced down upon the top of the filler neck and turned, though spaced therefrom by the washer K,

The other end of the resilient cli H is formed with the over-engaging hoo piece H which, when the cap is in the position of closure on the neck, which has just been described, engages under the then substantially horizontal face of the link D and cooperatively with the enga ement of its compganion clip iii-flange section 3 already referred to, serves to hold the parts in similarly assembled relation, subject to the inton tional spacing of the cap from the top edge pivotal y p of the filler neck by the washer K. Either of these clip elements alone would probably be suflicient to hold the cap in position of closure with res ect to the filler neck, but the use of both 0 them, H and H also serves to reduce the possibility of rattling of the parts to a minimum.

Upon reference to Figures 4, 5, and 6, itwill be noted that after the holdin clippoints have been disengaged from the ange B and the under face of the link D respectively by manual turning of the cap G, the subsequent lifting of the cap, combined with the pivotal anchorage thereof which the link D affords, results in the movement of the cap as a whole in a direction generally lengthwise of the extent of the link D about the pivoting ears B as a center thus throwing the cap increasingly to one side of the extended bounding lines of the filler neck, until, when the end of this swingin movement is reached, the cap and indeed a l but the inner end of the link D lie wholly outside thereof, causing no more interference with the free access of ahose nozzle to the top of the filling neck than would be the caseif the cap were of the threaded-onvarietyiand had been removed entirely. The reverse of the movement to that 'ust described as regards the cap G and the link D in turn results in the swing of the cap over the filler neck until-it is in practicall axial alignment therewith when a combine downward pressure and twisting movement exerted by the hand causes the lockinilengagement of the hooped points H and of the flange B and theunderface of the link D respectively in the manner already described. While m experience leads me to the belief that it 1s preferable to form the link D relatively rigid and the clip H relatively resilient, it should of course be understood as within the intended scope of this disclosure to form the link ,D relatively resilient, as from a single strap of sheet metal, and the terminally hooked anchorage clip H relatively rigid.

I It should also be noted that the end E of securing clip E, projecting as it does well beyond the rivet center F, serves, by engagement against theclip H, to limit the twisted throw ofthe cap G, sothat it cannot be turned further than is necessary to efi'ect the engagement with and disengagement from the flange B and the under face of the link D by the resilient ends H and H respectively of the clip H. Furthermore, this securing clip, as regards the attachment thereto of the upper end of the link D functions as well as a structural part of the cap G, enabling the link D to be made of such a length, extending as it does across the rivet center 1?, that the cap may be thrown entirely clear of the filler neck space when opening of the neck for insertion of a filling hose nozzle is desired; this would notbe the case if the upemar? per end of the link D were attached directly to the ca at the rivet center F. claim is:

1. In combination with a filler neck pro- 'vided with selectively positioned projections on its inner surface, a link member pivotally attached at one end to one of said projections in a position to extend therefrom beyond the axial center of said filler neck, a filler cap with which the other end of said link mem- "ber is operatively connected, and an anchorage clip supported by saidfiller cap, adapte when said cap is limitedlyrotated about its axis and that of the filler neck, to engage under the under surface'of said link, thereby lockin the ca in closure position over the top oi said fil er cap.

2. In combination with a filler neck, a cap :alftpted to close the same, means for limitof s aid cap relatively to said filler neck, comprisin a link connected at one of its ends to the sic of said filler neck and at the other end with the under side of said cap at an o erative point located on the opposite side of the common axial center of said filler neck and of said cap when positioned thereon from that point on said filler neck to which the first-named end of the link is connected, and an anchora e clip supported by said cap in position to e moved into operative gmgage- 3. In combination with an interiorly' rmitting relative unseating movement ,ment with one side of the filler neck and with flanged filler neck, a tethered closure therefor comprising a cap, a plurality of clip members carried on the under side thereof, and a link member pivotally connected at one end to the filler neck and at its other end to-the end of one of said cli members, whereby when the cap is in osition of closure over the filler neck said lin is positioned substantially transversely of the neck and is interlockin ly engageable by one end of the other of sai clip members upon the manually induced 'rotative movement of said ca about its axis, the other end of said clip at t e same time operativel engagin under an adjacent portion of the ange on 't e filler neck.

4:- lhe combination, with an inwardly bility', with respect thereto and with whichthe other end of said link member is connected and an anchorage clip also sup orted from the under side of said ca and adapted to become terminy interloc ed with link and with said flanged neck upon manually induced rotative movement of said neck.

combination with a filler neck and a ca adapted to seat upon the top edge thereo an anchorage clip attached to the under side of said cap and a link pivotally connected at one end with an interior'ly facing side of said filler neck and linked "at its other end to the under side of said cap said link be' adapted to be clampingly seized by one en of said anchorage clip contemporaneously with the eflecte operative engagement of the other end thereof with an adjacent ortion of the filler neck when the capis owered to-position ofclosure with respect to the latter.

In testimony whereof I sign this specification.
